Check Digit Verification of cas no

The CAS Registry Mumber 64277-86-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,2,7 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 64277-86:
(7*6)+(6*4)+(5*2)+(4*7)+(3*7)+(2*8)+(1*6)=147
147 % 10 = 7
So 64277-86-7 is a valid CAS Registry Number.

Nickel-Catalyzed Reductive Coupling of Aryl Bromides with Tertiary Alkyl Halides

Wang, Xuan,Wang, Shulin,Xue, Weichao,Gong, Hegui

, p. 11562 - 11565 (2015)

A mild Ni-catalyzed reductive arylation of tertiary alkyl halides with aryl bromides has been developed that delivers products bearing all-carbon quaternary centers in moderate to excellent yields with excellent functional group tolerance. Electron-deficient arenes are generally more effective in inhibiting alkyl isomerization. The reactions proceed successfully with pyridine or 4-(dimethylamino)pyridine, while imidazolium salts slightly enhance the coupling efficiency.
